Because there's nothing to remember :) In BASH, there's no builtin
function to to that.

I did that not so long ago but somehow don't remember it now and where I
did it. Here's one idea( from
http://www.daniweb.com/techtalkforums/thread41035.html):


You can get the path of your script with $0 :
SCRIPT_DIR=`dirname $0` #relative path

or, to get absolute path :
INITIAL_DIR=`pwd` # Save current dir
cd `dirname $0` # Go to script dir
SCRIPT_DIR=`pwd` # Save script dir
cd ${INITIAL_DIR} # Go back to initial directory
